Since the reinstall, there's been no sound in Linux. Xubuntu has output no sound. Found the following solution on the Ubuntu Forums.
Edit the alsa config file:
sudo mousepad /etc/modprobe.d/alsa-base
Added the following lines at the bottom of the file:
# Fix for Toshiba sound. From Ubuntu Forums options snd-hda-intel model=auto
We'll see how it works at the next reboot.
